LBC846BLT1G

LRC · Bipolar (BJT) · SOT-23

LBC846BLT1G from LRC, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 BASE input Base terminal of the NPN silicon transistor; the datasheet's emitter-base voltage rating VEBO is 6.0 V for LBC846 and LBC847/LBC850 and 5.0 V for LBC848/LBC849.
2 EMITTER passive Emitter terminal of the NPN silicon transistor; continuous collector current IC is rated at 100 mAdc maximum.
3 COLLECTOR passive Collector terminal of the NPN silicon transistor; collector-emitter voltage VCEO is rated 65 Vdc for LBC846, 45 Vdc for LBC847/LBC850 and 30 Vdc for LBC848/LBC849.
